The remaining pairs of switch lugs will be in a position
10、 above and below each of the remaining four connector center conductors. ( ) Hold the switch firmly in this position and tighten the control nut. ( ) Bend the ground lug downward with the blade of a screwdriver until it touches the long switch lug. Solder the two lugs together. Page 7 re*:w-=*- G R

14、 Place the knob on the switch shaft so the pointer is toward . Tighten the setscrew in the knob securely. You may now rotate the switch as desired. NOTE: You may wish to hang the Coaxial Switch on a wall or on an equipment enclosure. A mounting bracket has been furnished for this purpose. Any two of
15、 the opposite screws holding the rear cover plate may be removed to install the mounting bracket in the following step. If you do not wish to use the mounting bracket, skip the next step and also the third step (which tell you to install the mounting bracket). ( ) Note the numbers on the top cover a
16、nd remove the two screws opposite the 2 and the C. ( ) Place the blue and white label on the rear cover so the stamped numbers are positioned as close to two adjacent screw heads as possible. Positioning the label in this manner will permit you to read these numbers after the mounting bracket is ins
17、talled. NOTE: The Model Number and Production Series Number of your kit are shown on this label. Refer to these numbers in any communications you have with the Heath Company about this kit. ( ) Install the mounting bracket on the rear cover plate with two 4-40 x 114 flat head screws a s shown in the
18、 Pictorial. This completes the Step-by-step Assembly of your Coaxial Switch. You will be instructed to apply the decals from your label set during the Installation and Applications section which follows. C = * : * - . L = * Page 9 INSTALLATION AND APPLICATION NOTE: There are many ways that your Coax
19、ial Switch may be installed and there are various applications for its use. One method for installing the Switch is outlined below, and two methods for its use will be covered. Your individual needs will dictate your specific application. INSTALLATION Refer to Figure 1 for the following steps. ( ) P
20、lace the Switch against the wall or panel where it is to be installed. Mark the tip of each keyhole slot in the mounting bracket on the selected surface. ( ) Drill 3/32 holes at the marked locations. ( ) Turn the two k6 x 518 sheet metal screws into the holes until only 1/8 of the shank is showing.
21、Hang the mounting bracket onto the two screws; then tighten the screws securely. ( ) Loosen the thumbnut on the ground connection screw. Place the earth-ground lead between the two flat washers; then tighten the thumbnut securely. B A R Figure 1 Page 10 c - = - * - - - & J APPLICATIONS Refer to Figu
22、re 2 for the following steps. Primary Method ( ) Connect a dummy load to connector #4. Connect the transceiver (through a reflected power meter, if one is used) to the C (common) connector. Then connect from one to three antennas to connectors #1 through #3. Alternate Method (requires two Coaxial sw
23、itches) Refer to Figure 3 for the following steps. ( ) Connect the C (common) connectors of two coaxial switches together with a length of RG-8/U coaxial cable. Connect up to three transceiver units to connectors #1 through #3 on one Coaxial Switch. Then connect up to three antennas to connectors #I
24、 through #3 of the other coaxial switch. ( i 1 hen you have chosen the arrangement that best suits your requirements, select the appropriate decals in your label set. Remove those selected, one at a time, from the paper backing and press each into place over the embossed circles on the front panel o

WARNING: DO NOT OPERATE THE TRANSMITTER INTO THE COAXIAL SWITCH WHEN THE POINTER IS AT THE OR THE POSITION. When the Switch is in either of these positions, the transmitter is connected to an open circuit.

In either event, remove the rear cover from the switch assembly and carefully inspect each solder connection. Be sure that no solder has run from any of the
31、 center conductors to the metal parts of the assembly. If a circuit is known to be open, try moving the switch lugs where they touch the coaxial jack center It is suggested, if there still appears to be a problem, that you reheat each solder conductors. Be sure both the upper and lower switch lugs n
